The P piece 15 and the fixing screw 16 of the fixed tubular member 15 have an increased number of parts and a complicated structure. SUMMARY OF THE INVENTION 10 15 Ministry of Economic Affairs Intellectual Property Office Employee Consumption Cooperative Printing 20 ^ In view of this situation, an object of the present invention is to provide a clamping device capable of rapidly changing the clamping range while reducing the number of parts and having a simple structure. In order to achieve the object, the invention of claim i has the feature of J: a domain having a guide hole which can be abutted against the clamped object _i, the touch, and the first contact; - a threaded rod which is free to move in the longitudinal direction and has an outer screw when the outer circumference is "can be clamped at the front end of the first contact portion, the contact portion of the disc to grip the object; the nut member, the inner wall thereof And there is an inner crepe that can be integrated with the external thread, where A has a keeper, 2, the outer circumference of the threaded rod is at the second contact; the rotation between the 3 holes causes the internal thread to rotate relative to the external thread The axial movement of the drought; the rotation restricting portion = !=Γ; and the first contact portion of the contact portion and the threaded rod in the main body close to the guide hole are in a free state, and the rotation is performed; After the nut member is moved to the position on the threaded rod, the threaded rod is moved axially. The paper size is applicable to the Chinese version. (4) The first contact portion and the second f member cannot be rotated by the rotation restricting portion 5. In this way, the clamping range between the rotation and the lower part of the brother can be roughly adjusted. The female member is not placed, so that the shirt is rotated to adjust the position of the second contact portion. At this time, the object is clamped between the screw portion 2 and the second contact portion. By rotating the nut portion by the finger, the nut can be quickly changed to the first screw, and the operation can be performed more quickly. Therefore, the 10 (10) component and the fixed tubular member are fixed, so the nut is only required outside the rod. There is no need for the Ministry to guide the 5 pupils. Even in the main body, it is not specially made, so that the cost can be further reduced. 15 = In the case of the case, the 'rotation restricting member is a hole portion, the inner wall of which has a bright portion: the shape of the outer shape' can accommodate the nut member (the inner wall FT of the request item 2 is formed in the hole portion to accommodate the nut member, the hole portion Roughly all = the rotation of the nut member, so that when the threaded rod is rotated, the screw can be stably fixed, and the rotation of the threaded rod is also easy. Moreover, the nut member is preferably a hexagonal nut (request 2 of the request 3) Therefore, the nut member can utilize the commercially available hex nut: and the monthly b can further reduce the cost. [Embodiment] Hereinafter, the first embodiment of the invention mounting device for mounting the work lamp will be described with reference to Figs. 1 to 3 . In the embodiment, the main body 21 is substantially c-shaped, 20 1292025 A7 B7 5. Description of the invention (The Ministry of Economic Affairs, the Intellectual Property Office, the employee consumption cooperative printed on the upper portion 21a is provided with a mounting portion 22 for the device work lamp (not shown). A first contact portion 23 that is substantially adjacent to the object A to be clamped and has a shape of "A" is provided below the mounting portion 22. The lower portion 21b of the main body 21 and the first contact portion 23 are provided. phase As shown in FIG. 3, a circular guide hole 24 penetrating vertically is formed, and a hole portion 25 having a hexagonal inner wall is formed above the guide hole 24. There is no internal thread on the inner wall of the guide hole 24. The rotation restricting portion that can accommodate the hex nut 26 is configured as follows. In the main body 21, a guide wall 27 extending in the vertical direction is provided inside the intermediate portion 21c between the upper portion 21a and the lower portion 21b. The threaded rod 28 of the thread 28a passes through the guide hole 24 and is free to move in the extension direction of the guide bow hole 24. The upper end of the threaded rod 28 is provided with a second contact portion 29 facing the i-th contact portion 23, The lower end is provided with a handle 30 for rotating operation. The second contact portion 29 can be moved along the guide wall 27 but cannot be rotated. The threaded rod 28 and the second contact portion 29 are connected in a relatively rotatable state. The inner wall of the hex nut 26 has an internal thread 26a that can engage the external thread 28a of the threaded rod 28. The hex nut 26 is provided to be rotatable between the second contact portion 29 and the lower portion 21b of the body 21 on the outer circumference of the threaded rod 28. The hex nut 26 constitutes the nut member of the present invention The product is sold in the market. Once the hex nut is rotated, the internal thread 26a is rotated forward and backward with respect to the external thread 28a, and the hex nut 26 is moved relative to the axial direction of the threaded rod 28. The inner wall of the pocket portion 25 of the body 21 substantially conforms to the hex nut 26. The shape is such that it can accommodate the hex nut 26. Further, in the above configuration, the clamping range between the first contact portion 23 and the second 10 15 gauge line 1292025 A7 B7 is adjusted, and the contact portion 29 is described (6). In the case of B, as shown in FIG. 1, the hex nut 26 is separated from the hole portion 25 as the rotation restricting portion and is in a free state. By rotating the hex nut 26 with respect to the threaded rod 28, the hex nut can be made relative to the threaded rod. 28 axial movement. At this time, the hexagonal nut 26 is rotated by a finger, so that the hex nut 26 moves rapidly axially with respect to the threaded rod 28. After the hex nut 26 is moved to the appropriate position, the threaded rod 28 is axially pulled, and the hex nut 26 is housed in the hole portion 25 of the main body 21 (refer to Fig. 2). By accommodating the hex nut 26 in the hole portion 25, the hex nut 26 10 cannot be rotated, and thus the clamping width B between the first contact portion 23 and the second contact portion 29 is largely adjusted. In this state, the hex nut 26 cannot be rotated, and the handle 30 is controlled by a finger to rotate the threaded rod 28 to finely adjust the position of the second contact portion 29. By clamping the object A between the first contact portion 23 and the second contact portion 29, the mounting device can be fixed to the object. Then, by mounting the work lamp on the mounting portion 22 of this mounting device, the work lamp and the mounting device can be attached to the object A. Printed by the Intellectual Property Office of the Ministry of Economic Affairs, the employee consumption cooperative. In the first embodiment, the following effects were obtained. That is, when the clamping width B between the first contact portion 23 and the second contact portion 29 is adjusted, the hex nut 26 in the freely rotating state is rotated by a finger, and the hex nut 26 20 is moved relative to the threaded rod 28, and The clamping amplitude B is quickly adjusted. In such a configuration, in addition to the main body 21 and the threaded rod 28, only the hex nut 26 is required, and the number of parts is reduced as compared with the conventional clamping device which requires the cylindrical member and the fixing screw for fixing the cylindrical member. The structure is also simplified. Even in the guide hole 24 of the main body 21, it is not necessary to form an internal thread. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210x297 mm) 1292025 Α7 5, invention and description (7) B7 pattern. Moreover, the hex nut 26 is a commercially available product, which reduces the cost in one step. It must be specially made, and I, by using the shape of the hex nut 26: a rotation restricting portion that restricts the rotation of the hex nut 26: the hex nut 26 is accommodated in the portion 25, and the nut of the hole portion 25 can be inserted into the hole at the hole portion 25 The rotation of 26, so the 'rotating screw ^ king inner wall limits the six female % can be stably fixed when the 'hexagon screw.
